Shock and sympathy were the initial reactions from around the world to a shooting rampage that left 26 people dead, including 20 children, at a Connecticut elementary school. Australian Prime Minister Julia Gillard described the attack as a "senseless and incomprehensible act of evil."

"Like President Obama and his fellow Americans, our hearts too are broken," Gillard said in a statement.

The gunman killed his mother at home before opening fire Friday inside the school in Newtown, Connecticut, killing 26 people, including 20 children, police said. The body of the killer, identified as 20-year-old Adam Lanza, was also found at the school.

"As parents and grandparents, as brothers and sisters, as friends of the American people, we mourn the loss of children, aged only 5 to 10 years, whose futures lay before them," Gillard said. "We mourn the loss of brave teachers who sought only to lead their students into that future but were brutally murdered in a place of refuge and learning."

Australia confronted a similar tragedy in 1996, when a man went on a shooting spree in the southern state of Tasmania, killing 35 people. The mass killing sparked outrage across the country and led the government to impose strict new gun laws, including a ban on semi-automatic rifles.

Gillard's sentiments echoed those of British Prime Minister David Cameron, who said he "was shocked and deeply saddened" to learn of the "horrific shooting."

"My thoughts are with the injured and those who have lost loved ones," he said. "It is heartbreaking to think of those who have had their children robbed from them at such a young age, when they had so much life ahead of them."

There have been several mass shootings in 2012 alone, and on Friday President Obama said politicians will need to come together to take action regardless of the politics. NBC's Tom Costello reports.

In Japan, where guns are severely restricted and there are extremely few gun-related crimes, public broadcaster NHK led the noon news Saturday with the shooting, putting it ahead of an update on the final day of campaigning before Sunday's nationwide parliamentary elections.

NHK, which had a reporter giving a live broadcast from the scene, said that five of the children at the school were Japanese, and that all five were safe. Its report could not immediately be independently confirmed.

Several Japanese broadcasters ran footage from Newtown, showing scenes of people singing outside churches Friday evening, as well as part of President Barack Obama's tearful press conference.

In China, top of the newsThe attack in Connecticut quickly consumed public discussion in China, rocketing to the top of topic lists on social media and becoming the top story on state television's main noon newscast. China has seen several rampage attacks at schools in recent years, though the attackers there usually use knives. The most recent attack happened Friday, when a knife-wielding man injured 22 children and one adult outside a primary school in central China.

Much of the discussion after the Connecticut rampage centered on the easy access to guns in America, unlike in China, where even knives are sometimes banned from sale. But with more than 100,000 Chinese studying in U.S. schools, a sense of shared grief came through.

"Parents with children studying in the U.S. must be tense. School shootings happen often in the U.S. Really, can't politicians put away politics and prohibit gun sales?" Zhang Xin, a wealthy property developer, wrote on her feed on the Twitter-like Sina Weibo service, where she has 4.9 million followers. "There will always be mental patients among us. They should not be given guns."

NBC News' Lester Holt reports how the day of a shooting massacre in Newtown, Connecticut unfolded, from the moment Newtown police received an emergency 911 call from the Sandy Hook Elementary School to the children and parents who share their grievances over the 28 killed, including the shooter himself, 20-year-old Adam Lanza.

In the Philippines, a spokeswoman for President Benigno Aquino III said, "What makes it more painful is that most of the victims were small children."

"Our deep condolences go out to the families, teachers and their loved ones. Our hearts and minds are with them and pray with them as they go through a very difficult time, especially with Christmas approaching," deputy presidential spokeswoman Abigail Valte told DZBB radio.
